Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
SDRs were created in 1969 to supplement a shortfall of preferred foreign exchange reserve assets, namely gold and U.S. dollars. [3] The ISO 4217 currency code for special drawing rights is XDR and the numeric code is 960. [4] SDRs are allocated by the IMF to countries, [3] and cannot be held or used by private parties. [5]

European Secure Software-defined Radio (ESSOR) is a planned European Union (EU) Permanent Structured Cooperation project for the development of common technologies for European military software-defined radio systems, to guarantee the interoperability and security of voice and data communications between EU forces in joint operations, on a variety of platforms.
At least five drone shows have been canceled, or have paused the use of the systems, after several drones struck a crowd at a holiday show in Orlando on December 21.. Universal Orlando, Orlando ...
Swimming is one of those athletic endeavors that soothes the mind while building muscle in a low-impact, easy-on-the-injuries way. It happens to be a sport that’s ideal for seniors, and once ...
Low bit depth SDRs such as an 8-bit design can be somewhat accurate, but as they distinguish much coarser differences in input levels, precision at the low end of the S scale will suffer. Even with a high quality SDR, it is worth keeping in mind that the S meter is measuring the strength of the signal at the 50 ohm input of the receiver, not at ...
